AB - AID TO MEASUREMENT LABORATORY WORKERS APPARATUS FOR REFERENCE-STANDARD TESTING OF PLATINUM-ALLOY THERMOCOUPLES UDC 536.511.089.6 V. M. Kavtrev, B. I. Dernov, I. A. Stafeeva, and A. N. Starostin The Verkhne-lsetsk Metallurgical Plant has developed a system for checking working plati- num-rhodium/platinum thermometers by reference to a standard thermometer of the same type at 700, 900, and II00~ this has passed metrological tests and is now a standard test system. This system differs substantially from the UTT-5A and UTT-6V that are routinely in production, since the latter use a comparison method. Figure i shows the block diagram of the new system, where M-2000 is a portable instru- ment containing an F-II6/I microammeter, PMT-12M is a switch, T is a thermostat, MTP-2 is a fast-response tubular oven, and KSP-3 is an electronic self-balancing potentiometer. The working characteristics are as follows: maximum oven temperature 1200~ oven power 1500 W (with two control stages in the power input), time needed to reach 1200~ i h, work- ing space 40mmdiam. x 500 mm, number of thermocouples that can be checked simultaneously 5, range of measurement in thermo-emf  ~V, overall error in measuring thermo-emf not more than i ~V, dimensions 1300 x 800 x i000
